The rings that I bought weaver web site said to use for a scope with 50mm objective lens. Im sure they would have worked if I went with the 0 moa mount.
When I was ordering the ken ferral mount the gentelman told me to use the the ferral low rings and that would give me about an 1/8 or 1/16 in between the barrel and the scope which I like and want(but I dont want to lose the extra 20 MOA) but I didnt have an extra $163 after buying the 308 and the scope and mount. I wish I did then I wouldnt be having this problem now.
I called weaver before ordering the rings to try to get there measurements on all those ring but Im still waiting for a call back which was about 2 weeks ago.

Thanks for your help.
Im going to go tomorrow to a sporting goods store about an hour way from me, which they said over the phone that they have all 3 sizes of the weaver rings so I am bringing the rifle and the scope with me to fit it the way it should be.
